Our Dodge Ram 2500 has always used some oil, but nothing out of the ordinary for how much its driven and the loads it as pulled. Recently we hauled an oversized load a bit too heavy for the truck. It has used or burned or ? quite a bit more since then. Added 2 quarts oil about 3 days after th heavy load. And just again (maybe a week after put in 2qts )we added another 2-2 1/2qts. >> Problem not yet fixed. Reasearching the solution ... Anyone know the fix?
